Microsoft is offering a deal on refurbished HDD's to upgrade your memory capacity if you own a Arcade or Core 360 console. There are a couple of deals to be had. One is simply the the HDD for $19.99. The other I know of is the HDD and 3 months of Live for $29.99. It seems to give the Live deal if you haven't connected to Live before and simply the HDD deal if you have.

All you need for the deal is your console serial number and console ID number. The Console Serial Number and Console ID are both located in the System Information area of the Xbox 360 Dashboard:

1. Turn on your Xbox 360 Console 2. Scroll right to the System area. This may also be System Settings depending on your version of the dash 3. Select Console Settings 4. Select System Info 5. Write down your Console Serial Number and Console ID

I bought a dead 360 harddrive on ebay for the case and I'm going to put the 120gig in there. It's supposed to be pretty simple. I got the original hard drive out of the case and all the software downloaded and ready. Just waiting for the drive, should be here any minute...slow UPS.
